MANNER 0F REPLACING RAILROAD-CARS UPON THE TRACK.

Specication of Letters Patent No. 4,232, dated October 11, 1845.

To all whom t may concern Be it known that I, SAMUEL H. BEAN, of thecity and county of Philadelphia and State of Pennsylvania, have inventeda new and useful Improvement, being a Mode of Replacing Cars That haveBun Off the Track, called Beans Car-Beplacer, which is described asfollows, reference being had to the annexed drawings of the same, makingpart of this specification.

Figure l, is a side elevation o-f the apparatus, and a section of a carolf the track and in the act of being replaced. Fig. 2, is a crosssection of ditto. Fig. 3, is a top or birds eye view of the rail roadtrack, and blocks, showing their positions in relation to each other.Fig. 4, is a perspective view of two of the inclined plane blocks. Fig.5, is a section of a modification of the apparatus. The. nature of thisinvention consists in replacing rail road cars that have run off thetrack, by drawing the wheels of said cars up inclined planes, parallelwith the track, formed on the upper surface of oblong blocks, placed infront of the several wheels, which inclined planes extend some distanceabove the top of the rail, and intersect transverse inclined planesformed on said blocks at right angles to the first mentioned, and

drawing said wheels on these transverse in,

clined planes, down which they slide, transversely, by the gravity ofthe car, to their proper positions on the track.

The blocks A may be of cast-iron or formed of wood, and covered orsheared on their wearing surfaces with sheet iron, and each have twoinclined planes formed on their upper surfaces at right angles to eachother. The one marked B1 extending from one end of said block, abouttwothirds its length, having ribs or tongues G, projecting from itssurface to guide the wheels o f the car in their ascent; and the otherplane B2 extending from one side of the block to the other, at rightangles to, and immediately in front of, the first mentioned one. Theseblocks are permanently connected together in pairs, by cross bars C, asuitable distance from each other, to correspond with the width of thetrack; so that when they are placed in their proper positions inrelation to the track the lower terminus of the transverse inclinedplanes will be on a line and flush with the tops of the rails F.

Then the car has run off the track, a pair of these blocks are placed infront of each pair of wheels od, in the manner represented in thedrawing, being connected together and held in their positions bylongitudinal rods D. The wheels of the car are then drawn up thelongitudinalinclined planes B1, and on the transverse inclined planes B2and by the gravity of the car, they slide down said transverse inclinedplanes, to their proper positions on the track-the inclined planes B2being made convex in their cross section, to present as little surfacefor contact with the flanges of the wheels as possible to preventunnecessary friction.

When it is desired to replace an eight wheeled car, the forward set ofwheels may be replaced first, and the hind set afterward, or all may bereplaced at the same time.

A carriage E, Fig. 5, guided between two grooves, and resting onfriction wheels, may be placed on each of the transverse inclined planesB2, for conveying the cars down, instead of the wheels sliding over theconvex surfaces of the inclined planes; but regarding it as amodification of the same principle, and inferior to the first, I do notdeem it necessary to lay any claim to it in this application.

Vhat I claim as my invention and which I desire to secure by LettersPatent is- Replacing cars that have run off the track by drawing them uplongitudinal inclined planes B1, formed on blocks A of any suitablematerial connected together, and placed in front of the several wheels,and thence on to transverse inclined planes B2, formed on said blocks,immediately in front of said longitudinal planes, and terminating on alevel with the rails, down which said wheels are caused to slide, by thegravity of the car, to their proper positions on the track, as setforth.
